[evlatests] new executor software (v1.7.3)

[Rich Moeser]

A new version of the Executor has been released.

Changes and bug fixes (per Barry & Ken):
1) Changes to support two correlators. 
    - Send a "FINISH" observation document when a script is aborted.
    - Send an AntennaPropertiesTable document if running Widar.
    - Code inserted but not tested, in support of changing correlators 
in mid script.
2) Bugfix - setting frequencies for L302-3 and L302-4.
3) Time in a delay document for Widar is rounded to nearest millisecond.
4) Bugfix:  Converting the quadratic term in the delay polynomial for 
Widar to
seconds/day/day resulted in integer overflow.
